What is an H2S scavenger?

What is an H2S scavenger?

H2S scavengers are widely used in hydrocarbon processing facilities to maintain plant worker’s safety and productivity and eliminate their odor emissions. These specialized chemicals react selectively with and remove H2S to help meet product and process specifications.

What is the disadvantage of using solid H2S scavengers?

High H2S concentrations in produced gas creates safety hazards for operations, increases corrosion and sulfide-stress-cracking risks, and results in an export gas of lower value. To minimize these factors, various H2S removal methods can be utilized.

How does triazine scavenger H2S?

It is commonly used with sour shale gas production in the US. Triazine is primarily used for removing low (<100 ppmv/mmscf) levels of H2S. The triazine reacts preferentially with the H2S and the reaction is not inhibited by the CO2, avoiding unnecessary chemical consumption.

How do I get rid of H2S scavenger smell?

Make a paste of vinegar and baking soda, rub over your hands to lift the odor and rinse under cold water.

Which is the most common liquid H2S scavenger?

Triazine Triazine, the most commonly used liquid H2S scavenger, is a heterocyclic structure similar to cyclohexane, but with three carbon atoms replaced by nitrogen atoms. Oilfield terminology of triazine differs from the IUPAC convention, triazinane.

Why is triazine used as a H2S scavenger?

H2S scavenging, or “gas sweetening,” is both a safety-critical and economic concern for ensuring trouble free upstream and downstream operations. This GATEKEEPER will discuss the use of triazine as a liquid H2S scavenger.

How is amine gas treated to produce sweetened gas?

2 from the upflowing sour gas to produce a sweetened gas stream (i.e., a gas free of hydrogen sulfide and carbon dioxide) as a product and an amine solution rich in the absorbed acid gases.

What are the benefits of removing H2S from oil?

We remove H2S from millions of barrels with Pro3®. Immediately remove H2S from crude oil, meet pipeline spec. benefits look like? Lower your lease operating expense, reduce chemical use by 50-75% as compared to glyoxal and MEA triazine.
